How do I safelist Constant Contact domains in a security filter?

Several of my subscribers, including my own personal account, did not receive my email. Constant Contact says the email was "blocked," but this is nonsense. I didn't block my own account! How to fix?

Hello @FrankV6 ,

If the emails you're sending have been blocked, then it's indicating a change to a security algorithm on the receiving end. Your account appears to lack self-authentication, despite having your own domain, so I'd strongly encourage you to set that up for your account to achieve the most reliable delivery. For further assistance on any of these elements, please speak with the Delivery team directly.
